摘要： Motion planning with implicit occupancy for autonomous systems includes obtaining a set of trajectories through a geographic region for an autonomous system, and generating, for each trajectory in the set of trajectories, a set of points of interest in the geographic region to obtains sets of points of interest. Motion planning further includes quantizing the sets of points of interest to obtain a set of query points in the geographic region and querying the implicit decoder model with the set of query points to obtain point attributes for the set of query points. Motion planning further includes processing, for each trajectory of a least a subset of trajectories, the point attributes corresponding to the set of points of interest to obtain a trajectory cost for the trajectory. From the set of trajectories, a selected trajectory is selected according to trajectory cost.

摘要： Techniques for localizing a vehicle include obtaining an image from a camera, identifying a set of image feature points in the image, obtaining an approximate location of the vehicle, determining a set of sub-volumes (SVs) of a map to access based on the approximate location, obtaining map feature points and associated map feature descriptors associated with the set of SVs, determining a set of candidate matches between the set of image feature points and the obtained map feature points, determining a set of potential poses of the camera from candidate matches from the set of candidate matches and an associated reprojection error estimated for remaining points to select a first pose of the set of potential poses having a lowest associated reprojection error, determining the first pose is within a threshold value of an expected vehicle location, and outputting a vehicle location based on the first pose.

摘要： A vehicle positioning method includes obtaining a front road image of a vehicle and a road feature map, determining a lateral offset using a road feature map of a front road image, and then determining a second location of a vehicle based on the road feature map, a first pose, a local map corresponding to the first pose, and the lateral offset.

摘要： A system and method for performing visual localization is disclosed. In aspects, the system implements methods to generate a global point cloud, the global point cloud representing a plurality of point clouds. The global point cloud can be mapped to a prior map information to locate a position of an autonomous vehicle, the prior map information representing pre-built geographic maps. The position of the autonomous vehicle can be estimated based on applying sensor information obtained from sensors and software of the autonomous vehicle to the mapped global point cloud.

摘要： Techniques and systems are provided for localization of an apparatus. For instance, a process can include: obtaining a map of an environment, the map including a map point representing an object in the environment; obtaining image data including the object in the environment, wherein the image data is associated with a camera pose; obtaining point information from the obtained image data, the obtained point information describing two or more points of the object in the obtained image data; determining whether to associate the point information with the map point based, at least in part, on a comparison of the map point and an estimated point, wherein the estimated point is estimated based on the camera pose and point information; and based on the determination to associate the point information with the map point, associating the point information with the map point to localize an apparatus.

摘要： A map in a cloud service stores physical objects previously detected by other vehicles that have previously traveled over the same road that a current vehicle is presently traveling on. New data received by the cloud service from the current vehicle regarding new objects that are being encountered by the current vehicle can be compared to the previous object data stored in the map. Based on this comparison, an operating status of the current vehicle is determined. In response to determining the status, an action such as terminating an autonomous navigation mode of the current vehicle is performed.

摘要： Aspects presented herein may enable a navigation application of a UE to feed its calculated navigation route information to a PE of the UE to aid the PE computing positioning estimations to improve positioning accuracy. In one aspect, a UE estimates a current location of the UE based on a set of positioning measurements and time update predictions using a positioning engine. The UE calculates real-time navigation route information using at least one navigation application based on the current location of the UE, a destination of the UE, and map information. The UE changes or verifies a set of positioning estimations performed by the positioning engine based on the real-time navigation route information from the at least one navigation application.

摘要： A method for providing map data which include position information for first landmarks of a first landmark class, collecting environment data, and determining a position of the mobile unit. Training data are generated and stored for the first landmarks based on the position of the mobile unit, the collected environment data and the position information. Based on the training data, a first detector module is generated for detecting the first landmark class. The position determination system includes a memory unit for providing map data which include position information for first landmarks of a first landmark class, a data acquisition unit for collecting environment data, a localization unit for determining a position of the mobile unit, and a processing unit for generating and storing training data based on the position of the mobile unit, the collected environment data and the position information for the first landmarks.
